17、e structure (FOPS) standard of its own. It is recognized that there are various classes and sizes of forestry machinery that operate in a variety of environmental conditions as well as variations in log size the machines are capable of handling. Therefore, two alternative levels of acceptance criter
18、ia are given. DIN ISO 8083:2016-06 6 1 Scope This International Standard establishes a consistent, reproducible means of evaluating characteristics of falling-object protective structures (FOPS) under loading, and prescribes performance requirements for a representative specimen under such loading.
19、It is applicable to mobile or self-propelled, specially designed forestry machines as defined in ISO 6814. NOTE Research work is being done to develop a test method and criteria for certain polycarbonate materials and constructions where the present requirement levels may not be adequate. 2 Normativ

24、ructural members arranged in such a way as to provide operators with reasonable protection from falling objects (e.g. trees, rocks) DIN ISO 8083:2016-06 7 3.2 deflection-limiting volume DLV orthogonal approximation of large, seated, male operator as defined in ISO 3411 wearing normal clothing and a
25、protective helmet 3.3 roll-over protective structure ROPS system of structural members whose primary purpose is to reduce the possibility of a seat-belted operator being crushed should the machine roll over NOTE These structural members include any subframe, bracket, mounting, socket, bolt, pin, sus
26、pension or flexible shock absorber used to secure the system to the machine frame, but exclude mounting provisions that are integral with the machine frame. 4 Laboratory tests CAUTION Some of the tests specified in this International Standard involve the use of processes which could lead to a hazard
27、ous situation. 4.1 Apparatus 4.1.1 Standard laboratory drop test object, made of steel, as shown in Figure 1. 4.1.2 Means of raising the standard laboratory drop object to the required height. 4.1.3 Means of releasing the standard drop test object so that it drops without restraint. 4.1.4 Hard surfa
28、ce, of such firmness that it is not penetrated by the vehicle or test bed under the loading of the drop test. 4.1.5 Measuring device, to determine whether the FOPS enters the deflection-limiting volume during the drop test. 4.2 Test conditions 4.2.1 DLV and its location The DLV and its location shal
29、l be in accordance with ISO 3164. The DLV should be fixed firmly to the same part of the machine as that to which the operators seat is secured, and should remain there during the entire formal test period. DIN ISO 8083:2016-06 8 Dimensions in millimetres NOTE Dimensions d and l are optional, depend
30、ing on the mass of the test object required to match the drop height that will provide the energy specified in 4.3.4. For example, for a drop test object mass of 227 kg: d = 255 to 260 mm; l = 583 to 585 mm. aMay be drilled and tapped for a lifting eye. Figure 1 Standard laboratory drop test object
31、DIN ISO 8083:2016-06 9 4.2.2 Measuring accuracy The accuracy of the measuring device (4.1.5) used to measure the deflection of the FOPS and of the energy applied to the FOPS shall be in accordance with Table 1. Table 1 Measuring accuracy requirements Measurement Accuracy aDeflection of FOPS 5 % of m
32、aximum deflection measured or 1 mm Energy applied to FOPS 5 % of energy applied aThe percentages are nominal ratings of the accuracy of the instrumentation and shall not be taken to indicate that compensating overtest is required. 4.2.3 Machine or test bed condition 4.2.3.1 The FOPS to be evaluated
33、shall be attached to the machine structure as it would be in actual machine use. A complete machine is not required; however, the portion to which the FOPS is mounted shall be identical to the actual structure, and the vertical stiffness of any test bed used shall be not less than that of an actual
34、machine as described in 4.2.3.2. 4.2.3.2 If the FOPS is mounted on a machine, the following requirements apply: there are no limitations on customary attachments and/or payload; all suspension systems, including pneumatic tyres, shall be set at operating levels; variable suspensions shall be in the
35、maximum stiffness range; all cab elements, such as normally removable windows, panels or non-structural fittings, shall be removed so that they do not contribute to the strength of the FOPS. 4.3 Test procedure 4.3.1 The test procedure shall consist of the operations given in 4.3.2 to 4.3.6, in the o
36、rder listed. 4.3.2 Place the standard laboratory drop test object (4.1.1) on the FOPS top (small end down) at the location designated in 4.3.3. 4.3.3 The small end of the object shall be entirely within the vertical projection of the DLV, on the FOPS top. The centre of the object shall be at a point
37、 which depends on whether major, upper, horizontal members of the FOPS do or do not enter the vertical projection of the DLV on the upper part of the FOPS, as follows. a) Case 1: When major, upper, horizontal members of FOPS do not enter the vertical projection of the DLV on the upper part of the FO
38、PS. The centre of the drop test object shall be at that point which has the greatest possible sum of perpendicular distances (x + y in Figure 2) from the major, upper, horizontal structural members. b) Case 2: When major, upper, horizontal members of FOPS do enter the vertical projection of the DLV
39、on the upper part of the FOPS. DIN ISO 8083:2016-06 10 1) Where the covering material of all the surface areas above the operator is the same but of unknown thickness, the centre of the drop test object shall be in the surface of greatest area. This area is the projected area of the DLV without majo
40、r, upper, horizontal members. The centre of the drop test object shall be at that point, within the surface of greatest area, which has the greatest possible sum of perpendicular distances (x + y in Figure 2) from the major, upper, horizontal structural members. 2) Where different materials are used
41、 in different areas above the operator, each area in turn shall be subjected to a drop test. 4.3.4 Raise the drop test object vertically to a height above the position indicated in 4.3.2 and 4.3.3 to develop an energy of 5 800 J or 11 600 J based on the mass of an object shaped as shown in Figure 1.
42、 Two energy levels are given: national authorities may choose the level of requirement according to local conditions such as log size, etc. The drop test object shall be aimed to impact at a location on the FOPS to produce the maximum deflection. 4.3.5 Release the drop test object so that it falls f
43、reely onto the FOPS. 4.3.6 As it is unlikely that the free fall will result in the drop test object hitting at the location and/or in the attitude of 4.3.2 and 4.3.3, the limits given in 4.3.6.1 to 4.3.6.3 are placed on deviations. 4.3.6.1 The initial impact of the small end of the drop test object
44、shall be entirely within a circle of 200 mm radius (the centre of this circle is to coincide with the vertical centre line of the drop test object as positioned according to 4.3.2 and 4.3.3) but not on any major, upper, horizontal member. 4.3.6.2 The first contact between the drop test object and th
45、e FOPS shall only be along the small end of the drop test object and/or the radius contiguous to that end (see Figure 1). 4.3.6.3 There is no limitation on location or attitude of subsequent impacts due to rebound.

46、zontal member Figure 2 Drop test impact points DIN ISO 8083:2016-06 11 5 Performance requirements 5.1 Protective properties The protective properties of the FOPS system shall be estimated by the ability of the cabin or protective structure to retain its safety zone intact after the impact. The DLV a
47、s defined in 3.2 and specified in 4.2.1 shall not be entered by any part of the protective structure under the first or subsequent impact of the drop test object. If the drop test object penetrates the DLV, the FOPS shall be deemed to have failed. 5.2 Additional ROPS requirements Where the structure
48、 is intended to fulfil both ROPS and FOPS requirements, it shall also meet the performance requirements for the appropriate ROPS as given in ISO 8082. Where roll-over protection is not required, a different structure may be used to support the FOPS as long as the DLV is not entered in the test. Shou
49、ld the same structure be used for both ROPS and FOPS evaluations, the drop test procedure shall precede the ROPS loading. The removal of impact dents or replacement of the FOPS is permitted. The indicated volume of a ROPS and FOPS having four or more vertical members need not entirely enclose the DLV. Nor is it intended that a simple (two-post) frame be excluded as either a FOPS or ROPS. 5.3 Temperature and material requirements 5.3.1 General The laboratory evaluations sh
